The National Instruments PXI-2796 RF Multiplexer Switch Module (Part Number: 782356-01) is a high-performance 50 Ω, 40 GHz dual 6x1 PXI RF multiplexer switch solution. This module features a high-density, unterminated multiplexer design with two redundant 6x1 multiplexer banks integrated into a single unit. The PXI-2796 is particularly suited for routing high-order harmonics from signal upconverter modules or for directing various power supplies to PXI RF signal downconverter modules. This RF multiplexer can accommodate a maximum input voltage of 30 Vrms, a maximum carry current of 0.6 Arms per channel, and up to 18 W of RF carry power at a 50 Ω load. It showcases exceptional performance specifications, including less than 1.1 dB insertion loss, less than 2.2 voltage standing wave ratio (VSWR), greater than 45 dB of open channel isolation, and 5 W of RF carry power while operating at frequencies below 40 GHz. The PXI-2796 is outfitted with non-latching electromechanical relays that utilize a beryllium copper, gold-plated contact material, ensuring a 15 ms operate/release time and a mechanical life rated for 2 million cycles. The module has 14 SMA 2.9 jacks for I/O connectivity and conforms to a 3U, two-slot PXI form factor, with physical dimensions of 21.6 cm x 4.1 cm x 13.0 cm. It employs PXI trigger lines 0 to 7 for input and output trigger signals and operates at a power requirement of 6 Watts from a 12 V supply. The recommended channel switching speed is 5 channels per second, making it a versatile choice for advanced RF testing and measurement applications.
